Study On The Effect Of SQ Microbial Inoculants On Dead Carcasses Of Pigs

Nowadays,many pig carcass were produced from swine industry.The application of biotechnology for corpse resource disposal is now one of the important ways to solve pig carcasses pollution.The SQ microbial agents were added to ferment compost of pig corpse,pig manure,rice bran and peat soil in this paper.The results are as follows:The selection of the fermentation process parameters.According to the analysis of temperature change,degradation of organic matter in the fermentation process,the effects of fermentation were best when inoculation quantity was controlled in 2%,initial moisture content of compost should be controlled on 50%,the initial C/N ratio of compost is 28:1 and the compost were turned over every other 12 hour in this test.The pathological analysis of the fermentation products.pseudorabies virus,foot-and-mouth disease virus,enterotoxigenic escherichia coli,Bacillus Erysipelatous of pig carcasses before fermentation were positive,and they were all negative after high temperature fermentation in fermentation products.Analysis of physicochemical properties of fermentation products Nitrogen,phosphorus,potassium,heavy metals,Escherichia coli and other physicochemical indicators were determined,the results show that the detection indicators have reached the "Microbial Organic Fertilizers"(NY 884-2012)stangdard value.
